HAND WHEEL.

Application filed. March 16, 1923. Serial No. 625,511.

This invention relates to a hand wheel, designedprimarily for use'as a valve handle although it can be used wherever it is desired to use a wheel as a handle whereby a structure can be rotated.

One of the objects of the invention is to provide a hand wheel which is formed of sheet metal, the parts being air-cooled, thus to prevent burning the hand of the user, as for example, when the wheel is applied to the stem of a gage cock.

Another object is to provide a hand wheel which does not require the use of asbestos or other insulating material and which affords a firm grip for the hand.

lVith the foregoin and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed without departing from the. spirit of the invention.

In the accompanying drawings the pre ferred form of the invention has been shown.

In said drawings:

Figure 1 is a detail view of the blank from which the hand wheel is formed.

Fig. 2 is a side elevation of the hand wheel, a part of its holding means being shown in section, the section being taken on the line 22, Fig. 3.

Fig. 3 is a transverse section of the hand wheel taken on line 3-3 of Fig. 2.

Referring to the figures by characters of reference, 1 designates a metal disk stamped from suitable sheet metal and provided with radial fingers 2 having their outer ends pointed as shown at 3. Openings 4 may be suitably arranged within the disk to allow the free passage of air for cooling purposes, and the central angular opening 5 can also be formed in the disk. As shown in Fig. 3, the disk is adapted to be shaped by stamping an annular channel 6 therein, thus to provide a central hub portion 7 and an annular outstanding portion 8. The fin- -ing disk.

gers 2 are curved inwardly with their points inturned as shown in Fig. 3. Two disks are provided, the same being oppositely disposed, and when theyv are assembled as shown in Fig. 3, the points of the fingers 65 will interfit as shown in Fig. 3, thus pro-' viding a skeleton-like circumferential portion forming a firm grip for the hand of the user but allowing air to circulate freely between the fingers. ()ne of the disks has lugs 9 struck therefrom and these lugs are adapted to be inserted through openings 10 formed in the other disk after which they can be bent outwardly as shown in Fig. 3, thus to hold the disks properly assembled.

The preferred manner of mounting the wheel is illustrated in Figs. 2 and 3. The stem 11 ofthe part to be rotated is formed with an angular end 12 adapted to extend through the openings 5 in the two disks and fit snugly therein so that one of the disks will bear against a shoulder 13 provided at the inner end of the angular portion 12. collar 14: is placed against the other disk and around the end of the stem after which a screw 15 is inserted in the stem and its head adjusted against the collar so as to force the collar-tightly against the adjoin- See Fig. 3. Thus the parts will be held firmly assembled.

It will be noted that a hand wheel such as described can be cheaply manufactured and provides all of the advantages of the more expensive handles.

What is claimed is 1. A hand wheel comprising opposed sheet metal disks having their central portions offset laterally in opposite directions respectively, means for holding the disks together, said offset ortions cooperating to form a hub, radial ingers at the periphery of each disk, the fingers on each disk being curved laterally, outwardly and inwardly, the fingers on one disk being curved oppositely to the fingers onthe other disk, the free ends of the fingers being tapered, the tapered end of each finger extending inwardly and wedging between the tapered ends of the adjacent fingers on the opposed disk, the free ends of all of the fingers be- 10.0

ing projected into the space defined by all each finger Wedging inwardlybetween the tapered ends of the adjoining fingers of the I opposed disk.

In testimony that I claim the foregoing as my own, I have hereto afiiXed my signature.
